Every Black Beauty Common Mode Choke and Balun is wound by hand, tested for CMRR and choking impedance, and built to commercial RF equipment standards — not consumer electronics standards. We use High Quality Fair Rite ferrite cores controlled for inductance and physical parameters, Ultraflex Silver Plated Copper Stranded wire, and environment resistant tie wraps rated to > 300°F. Every unit is housed in a Heavy Duty UV resistant ABS enclosure. These are not spec sheet claims, they are the actual components in every unit we ship.

We specialize in RF Common Mode Chokes and Baluns for HF amateur radio — products where quality directly determines station performance, RFI rejection, and noise floor
A poorly wound balun or choke can have dramatically lower CMRR than spec sheet numbers suggest. We publish real measured data because we stand behind what we build.
We are always available to answer your questions and help you find the right products for your needs. Plus, we offer competitive pricing and satisfaction guarantee by our "No Questions Asked" Return Policy.
With decades of experience in the electronics industry, we have established ourselves as a trusted provider of RF products.
